Handling Physical Evidence Location

Common questions
Frequently Asked
4
May a defense attorney refuse to present a client's planned perjured testimony?+
A defense attorney must first attempt to dissuade the client from committing perjury. If unsuccessful the attorney may refuse to present the false testimony and may disclose the perjury to the court as a last resort under applicable ethical rules.
Supporting sources
What obligations does a defense attorney have regarding physical evidence learned from a client?+
Client communications about the location of physical evidence remain privileged. A defense attorney who removes or alters evidence must turn it over to authorities while the underlying communication itself stays protected.
Supporting sources
How does a court evaluate whether a defense attorney provided ineffective assistance?+
The court examines whether counsel's performance fell below an objective standard of reasonableness and whether the deficient performance prejudiced the defense by creating a reasonable probability of a different outcome.
Supporting sources
Who decides whether to accept a plea offer in a criminal case?+
The client alone decides whether to plead guilty. A defense attorney must consult with the client and abide by that decision rather than accepting a plea based on instructions from a third party such as corporate counsel.
